G.R. No. L-36545. January 26, 1977
ESSO PHILIPPINES, INC. (now PETROPHIL CORPORATION), petitioner, vs. MALAYANG MANGGAGAWA SA ESSO (MME), PHILIPPINE FEDERATION OF PETROLEUM WORKERS (PFPW) and the COURT OF INDUSTRIAL RELATIONS, respondents.

FACTS

This case involves the execution of a final Supreme Court decision (G.R. Nos. L-26386 & L-26355, Feb. 27, 1971) which modified a CIR judgment in an industrial dispute. The Supreme Court had ordered the restoration of certain benefits and positions for Esso employees, specifically: (1) the abolished positions of assistant truck drivers/helpers and fillers; (2) transportation and meal allowances for employees assigned to the Manila International Airport (MIA) or JOCASP units; and (3) proper retirement benefits for employees compulsorily retired before age 60. When respondent union MME moved for execution, the CIR trial court initially dismissed the petition. However, the CIR en banc reversed this dismissal and ordered execution. Esso then filed the present petition for review, arguing that the benefits had been validly abolished by subsequent collective bargaining agreements.

ISSUE

The core issue is whether the benefits ordered restored by the final Supreme Court decision could be subject to execution, or whether they had been lawfully extinguished by subsequent collective bargaining agreements entered into between Esso and a different union, the CLU, which represented the employees after the strike.

RULING

The Supreme Court dismissed the petition and sustained the CIR en banc’s order of execution, but with specific qualifications. The Court held that a final and executory judgment must be executed as a matter of right. The subsequent collective bargaining agreements (CBAs) with the CLU, which allegedly abolished the restored benefits, could not automatically nullify the execution of the final Supreme Court ruling. The legal logic is that the final judgment had conclusively adjudicated the rights of the parties as of the time of the dispute. Any new agreement purporting to alter these adjudicated rights must be scrutinized to ensure it was freely entered into without vitiating circumstances. The Court ruled that the validity of these subsequent CBAs and their effect on the restored benefits was a separate issue that must first be determined in the proper forum (the National Labor Relations Commission, as the CIR’s successor). Therefore, execution must proceed, but payments of backwages and allowances were ordered only up to July 8, 1966—the expiry date of the pre-strike CBA—without prejudice to further payments pending the final determination of the validity of the succeeding agreements. Regarding retirement benefits, individual retirees were given the option to choose between the scheme under the final judgment or the benefits they had already received, with Esso barred from claiming reimbursement for amounts already paid.
